This invention relates to windows for railway cars, buses and other structures, and particularly structures where window sashes must or should be-relieved of edgewise shocks and jars and must be practically weather tight, and in some situations air tight, as where the structure or enclosure is air conditioned.

It has for its object a particularly simple and economical window embodying a buffer and sealing strip, wherein the buffer and sealing strip not only relieves the glass thereof of transverse shocks but also edgewise shocks.

More specifically, it has forits object a buffer and sealing strip channel-shaped in cross section for embracing the sash frame or itself forming the sash frame and embracing the glass pane and having the bottom of the channel formation so shaped that it is' thicker intermediate of its side edges than at its sides where it adjoins the sides of the channel formation, sothat upon being compressed in the channel of the window frame, the bottom portion bulges or expands in a direction edgewise of the sash against the edge of the sash or the glass pane and the bottom of u the channel of the window frame.

. r The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to 30 the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is a fragmentary elevation of a window structure embodying this invention and including a sash frame embraced by an outside frame of compressible material.

Figure 2 is an enlarged sectional view on line 2-2, Figure 1.

Figure 3 is a view similar to Figure 2 of a 40 slightly modified adaptation of the invention.

Figure 4 is a face view on a reduced scale of the window sash and sealing strip thereon.

Figure 5 is an enlarged isometric view of a double sash in which the glass panes are received in 45 a sash frame or seal of compressible material, as rubber, so that the seal constitutes the sash frame.

Figure 6 is a sectional view, similar to Figure 3, showing the glass panes as received in a com- 50 pressible sash frame without the metal frame shown in Figure 3.

I designates the sash frame, which, in Figure 2, is shown as provided with two glass panes 2 with an air space 3 between them. These arechannel in the sash frame I and as held apart by a spacer I, usually of rubber. Also, the channel of the sash frame I is provided with a lining l of rubber, or any suitable material.

The construction of the sash frame per se and l the assembly of the glass panes 2 forms no part of this invention.

8 designates the sealing strip or frame of elastic, resilient. compressible material, as some form of rubber. This is channel-shaped in cross sec- 10 tion, and the margins I of the side walls or flanges of the channel formation are provided 'withlips which press against the outer faces of the panes 2, and thus additionally seal and protect the joints between the glass panes 2 and the sash ll frame I. The margins I are so formed as tobe distorted and pressed against the glass panes, when the sash and the sealing strip 8 are under compression in the channel of the window frame. The strip 8 is continuous and when on the sash frame is under tension and provides a resilient, compressible, tirelike buffer strip and not transferred through the sash frame to the glass panes.

The bottom portion 8 of the channel formation is of greater thickness at its intermediate a portion in a direction edgewise of the sash than at its side portions where it adjoins the side walls or flange formation, and the bottom portion engages the edge of the sash only at the thickest point of the bottom portion, and like- 80 wise engages the bottom of the channel of the window frame only at the thickest point of the bottom portion. As here illustrated, the bottom portion 8 is substantially elliptical in cross section, so that its inner and outer walls 9, III are a convex or arcuate and engage the edge of the sash l and the bottom of the channel of the window frame at H and I2 respectively.

I! designates the window frame having a flange I forming one side of the channel of the win- 40 dow frame, and a removable flange Ill forming the other side of the channel. The edge face of the sash and the bottom of the channel of the window frame are of different contours from the inner and outer faces of the bottom portion 8 of the sealing strip, and as here shown, the edge face of the sash and the bottom of the channel of the window frame are flat. The removable flange I! of the channel of the window frame is clamped or held in position in any suitable manso ,ner, as by screws id.

- In mounting the sash in the window frame, the side I! is demounted and the sash frame with the sealing strip 6 thereon placed in the channel; thenthe side I! applied and clamped in position I by tightening of the screws 16. The clamping of the removable side IS in position compresses the sealing strip in a direction transversely of the sash, and hence applies a compressing force in a direction along the major diameter of the elliptical formation of the bottom 8 of the sealing strip 6. This clamping action not only clamps the resilient sealing strip between the sides H and I5, but also causes the bottom 8 to bulge in a direction edgewise of the sash frame, causing it. to press against the sash frame at H and against the bottom of the channel of the window pane at l2, thus tightly holding the sash in the window frame and cushioning the sash frame against shocks in all directions, and particularly in a direction edgewise of the sash.

In Figure 3, the sealing strip 60 is shown as applied to a single frame, the sealing strip having a bottom portion 80, similar to the bottom portion 8 (Figure 2.)

In either form of the invention shown, because the sealing strip is tensioned and because of the formation of the bottom of the channel of the sealing strip, not only are the glass panes sealed but also any strains transferred equally throughout and the sash and glass panes cushioned in all directions against shocks and jars.

In Figure 5, the glass panes 2 are shown as mounted directly in individual sash frames I! of compressible material, as rubber, formed with grooves l8 for receiving the margins of glass panes, so that the frame members I! are channelshaped in cross section. The bottom of the channel is formed elliptical as in Figures 2 and 3, and the portions of the bottom at opposite ends of the minor diameter of the elliptical formation, thrust, respectively, at l9 and 20 against the bottom of the channel of the window frame and the edge of the glass pane. These members H are compressed and distorted when the removable side l5 is clamped in position by means of the screws l6, as in Figure 2.

In Figure 6, a single glass pane is shown embodying the same features as shown in connection with the double sash of Figure 5. The glass is shown as ground oflf at the corners at 22. However, the elliptical bottom of the channel of the compressible frame member I1 thrusts against the bottom of the channel of the window frame at l9 and against the edge of the glass as at 20, as in the structure shown in Figure 5.

In both Figures 5 and 6, the frame members I! are compressible and resilient and placed under tension around the glass pane.

In the constructions shown in Figures 1, 2 and 3, the sealing strip 6 is an outer sash frame or section relative to the inner sash or section I; and in Figures 5 and 6, the sealing strip l1 constitutes the entire sash.

In any exempliflcation of the invention, the elliptical or semi-elliptical shape of the bottom of the channel formation of the compressible frame members 6, 60 or I! facilitates the placing of the sash into the window opening and the removal therefrom because while being so placed or removed, the portions of the members 6, 60,

' I! slide on the bottom of the window frame channel only at the end of the minor diameter of the elliptical formation. The elliptical formation alsocompensates for variations in both size and shape of window openings more readily than if these parts 6, 60, and I? were rectangular or other shape. When the removable sides I 5 of the channel of the window frame are clamped in position, these members 6, 60 and II are under compression and distortion in such direction as to hold them snugly in the window frame and also snugly and yieldingly support the glass panes.

For the purpose of holding a dehydrating or moisture absorbing agent for removing moisture from the air between the glass panes and thereby preventing clouding of the panes, a container 24 for a dehydrating material, as activated alumina, in granulated, block or cartridge form is provided, and as here shown, this is in the form of a trough extending along the upper margin of one of the glass panes and supported from the edge of the said pane. It is here shown as having an elongated side 26 extending into the glass groove of the sash frame of one of the members l1 and having a flange 21 hooking over the upper edge of the glass pane 20. This trough is spaced about from the other glass pane forming an air passage 28.
